In the design of the pressure pipe, pipe diameter is determined by the calculation, we must select the material pipe. The use of pipe materials for pressure pipe is based on the operating conditions of the medium (such as pressure, temperature) and the media characteristics of the decision.
Improper selection of materials, will result in a waste or buried accident risks. If you can use ordinary materials, pipe, pipe selection of more expensive materials, it increases the unnecessary investment in infrastructure. The use of acid-resistant stainless steel with carbon steel will directly affect the normal operation of the pressure pipe, and even leave the seeds. Therefore, the choice of pipe materials, designers must first understand the type of pipe, specifications, performance, use, it is best to investigate the pipe in other similar pressure pipe applications, and then in accordance with the following principles to determine the material pipe.
